What is spherical mirror explain with diagram?
A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors.
How do you draw a ray diagram for a spherical mirror?
Step-by-Step Method for Drawing Ray Diagrams
- Pick a point on the top of the object and draw two incident rays traveling towards the mirror.
- Once these incident rays strike the mirror, reflect them according to the two rules of reflection for concave mirrors.
- Mark the image of the top of the object.
What are the images formed by the spherical mirror?
The two rays, CY and DM are diverging rays and when extended behind the mirror, they appear to intersect each other at point M’. Therefore, the properties of the images formed here are formed behind the mirror, between the pole and principal focus (f), the images are diminished and are virtual and erect.
Why are spherical mirrors so called?
Spherical mirrors are the part of glass sphere whose inner or outer side is polished and non-reflecting. Most of the curved mirror is a spherical mirror. If the reflecting surface of a spherical mirror is concave,it is called a concave mirror. If the reflecting surface is convex,then it is a convex mirror.
What is called spherical mirror?
Answer: A mirror in which reflection takes place from a curved surface or in which the reflecting surface is curved is called a spherical mirror. They are derived from spheres. Most common types are- concave and convex mirrors.
What is spherical mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What is spherical mirror simple?
: a mirror with a surface that is either concave or convex and forms a portion of a true sphere.
What are the 4 rules of convex mirror?
For a convex mirror, if the object is at infinity the image will be a dot on the focal point. As the object moves from infinity toward the mirror, the image moves along the principal axis toward the mirror. When the object is right next to the mirror, the image will be right next to the mirror on the other side.
Why are mirrors spherical?
The light gets reflected from the surfaces. Any surface which is polished or in other words is shiny always acts like a mirror be it of any kind. The observation of light bouncing off or getting back from the surfaces is termed reflection.
